KNOCKDOWN DRAWER.

SPECIFICATION forming part of Letters Patent No. 786,398, dated April 4,1905.

Application filed July 21, 1904. Serial No. 217,514.

To (all whom, it may concern:

Be it known that I, FRANK O. ANDERSON, a citizen of the United States,residing at Jamestown, in the county of Chautauqua and State of NewYork, have invented a new and useful Knockdown Drawer, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear, and exact description.

The invention relates to the construction of folding drawers forknockdown furniture; and the object of my improvement is to make adrawer which can be easily knocked down or set up and locked in thesetup form without the use of additional meanssuch as hooks, nails,screws, and the likefor securing the parts in position.

In the drawings, Figure 1 is an elevation of the inner side of a drawerend with the drawerfront in dotted line and showing the groove for thedrawer-bottom, the dovetailed groove for the drawer-back, the dovetailedattachment to the drawer-front, and the tongued, grooved, and pinnedhinge in the drawer end. Fig. 2 is a plan view of a folded drawerwithout the bottom board. Fig. 3 is an elevation of the inner side ofthe drawer-back and an edgewise view of the same, showing thedovetail-shaped ends. Fig. 41 is a plan view of the drawer-bottom,showing the locking projection on the rear edge. Fig. 5 is a sectionalview of a lower corner of the drawer end and bottom and thedrawer-support, the main portion of the drawer being broken away. Fig. 6is a plan View of the upper edge of the drawer end at the hinge, showingmy preferred form of hinge with the bevelended meshing tongues. Fig. 7is a plan view of a portion of the drawer end and front, showingmodification of the hinged construction.

Similar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the drawer end, which is made with a roundedlower edge 1 1 to work in my drawer-support 12, which drawer-support ispreferably made after this form, as shown in my former Letters Patent,No. 7 02,389. This is not absolutely necessary, for any good form ofsupport would sustain my drawer but this form allows of complete freedomfor lateral displacement or removal. Drawer end 10 is dovetailed to thedrawer-front 13 in the usual manner. A groove 14 is cut near its loweredge for the drawer-bottom, and a dovetailshaped groove 15 is providedat the rear end for securing the back 16 and the rear corners of thedrawer. The two ends 17 of drawer-back 16 are cut in dovetail form tofit groove 15, so that the back 16 can be easilyslipped into theopposite grploves 15 on the inner side of the drawer en Drawer-bottom 18is formed with chamfered front and end edges 19 to fit correspondinggrooves 14 in the drawer ends and front. The rear edge of bottom 18 hasa projection 20 to engage a slot 21 in drawer-back 16. Drawer-bottom 18is made just the size desired for the drawer when set up, so that byspringing drawer-back 16 outwardly sufficient to allow projection 20 toenter slot 21 the drawer is locked securely in the set-up form.

In order to fold a drawer, it is apparent that the drawer ends 10 shouldfold inwardly onto the drawer-front. Accordingly a hinge 22 is providedin the drawer end preferably a short distance from the drawer-front, sothat the inwardly-folded parts of the drawer ends can fold within thesame. The drawer-back 16 is placed against the folded parts, and thedrawer so assembled can be placed in its regular drawer-opening in theframe, suitable provision having been made for knocking down said frame.The hinge 22 is preferably made with tongue-and-grooved parts which fitone another, as shown, and a pin 23 is inserted down through the centerof these intermeshing parts. This form of hinge is preferred, because itis simple, docs nottake any space outside of the regular drawer end, andis strong and durable, not weakening the drawer. The ends 24 of theintermeshing tongues are preferably made at a slight angle, as shown inFig. 6, so that when the inwardly-folding part of the drawer end comesout into line with the part attached to the drawer-froi'it it isstopped, and in consequence the back 16 is held more firmly in place ingrooves 15.

In Fig. 7 is shown two modifications of hinged joint 22, which-areneither of them as good as hinge 22, but which would serve a goodpurpose in folding in drawer end 10.

First. The drawer end 10 is made in two parts with abutting ends at 25,and a malleable sheet-metal V-shaped piece 26 is inserted in clefts inthe two parts, so that the angle comes at the line 25. The sheet-metalpiece 26 is held in place by suitable rivets 27, and it is apparent thatthe malleable sheet metal will bend at the angle, allowing of thefolding of the drawer for shipment and the setting of it up again.

Second. Substantially the same idea is shown at 28, wherein asheet-metal strip is inserted in the drawer end and drawer-front acrossthe angle of their abutment. In this latter modification, however, thedrawer end cannot be dovetailed onto the drawer-front, but a tenon 29 isprovided on the end of the drawer-front which fits a correspondingmortise on. the drawer end 10, and this tenon 29, in combination withthe metal piece 28 across the angle of the joining of the two parts,form a fairly-strong joint, and it is apparent that the entire side canbe folded inwardly by the bending of the malleable sheet-metal strip 28.

I claim as new 1. The combination in a folding drawer, of a suitabledrawer-front, drawer ends attached to the said front having hingestherein to 'fold inwardly, and a drawer bottom and back slidably mountedin suitable supporting-grooves in said ends.

2. The combination in a folding drawer, of a suitable drawer-front,drawer ends attached to the said front and having a tongue-andgroovedbisection in each end and pins passing through said intersecting tonguesand grooves to form hinges to fold the rear part of the drawer endinwardly, and a drawer bottom and back slidably mounted in suitablesupporting-grooves in said drawer ends.

3. The combination in a folding drawer, of a drawer-front, drawer endshaving hinges therein to fold inwardly, a drawer-back havingdovetail-shaped ends and opposite dovetail-shaped grooves in the drawerends to slidably receive said drawer-back, and a drawer-bottom slidablymounted in a supporting-groove in said end.

4. The combination in a folding drawer, of a drawer-front, drawer endsattached thereto having hinges therein to fold inwardly, a drawer backand bottom slidably mounted in suitable supporting-grooves in said ends,a projection on said drawerbottom, and the drawer-back provided with anopening for said locking projection.

5. The combination in a folding drawer, a drawer-front 13, drawer ends10 dovetailed to the front 13 and havinga tongue-andgrooved bisectinghinge 22 with pivot-pin 23 and angular ends 24, a drawer-back 16 havingdovetail-shaped ends 17 to slidably engage opposite dovetail-shapedgrooves in drawer ends 10, and a drawer-bottom l8 hav ing a projection20 to engage a locking-slot 21 in drawer-back 16, substantially as andfor the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANK O. ANDERSON.
